ASR - Alkali-Silica Reactivity

แปลว่า(Concrete Engineering) The reaction of aggregates, which contain some form of silica or carbonates with sodium oxides or potassium oxides in cement, particularly in warm, moist climates or environments, causing expansion, cracking or popouts in concrete.

Pozzolan (ASTM C 618)

แปลว่า(Concrete Engineering) A siliceous, or siliceous and aluminous material, which in itself possesses little or no cementitious value but will, in a finely divided form, such as a powder or liquid and in the presence of moisture, chemically react with calcium hydroxide at ordinary temperatures to form permanent, insoluble compounds possessing cementitious properties.

Waste minimization

แปลว่า(Environmental Engineering) The elimination or reduction of a waste prior to its generation. This is accomplished by process changes rather than waste treatment methods.

Reactive waste

แปลว่า(Environmental Engineering) A waste which; 1) reacts violently with water, 2) forms potentially explosive mixtures with water, 3) is normally unstable, 4) contains cyanide or sulfide in sufficient quantity to evolve toxic fumes at high or low pH, 5) is capable of exploding if heated under pressure, or 6) is an explosive compound listed in Department of Transportation (DoT) regulations. One of EPA's four hazardous waste properties.

Blast Cleaning (blasting)

แปลว่า(english) A process for cleaning or finishing metal objects by use of an air jet or centrifugal wheel that propels abrasive particles (grit, sand, or shot) against the surfaces of the workpiece at high velocity.

water glass

แปลว่า(เคมี) แก้วเหลว คือ potassium หรือ Sodium silicate ซึ่งละลายเหลวเหมือนน้ำเชื่อม ใช้เป็นส่วนประกอบในการทำสะบู่, ทำวัตถุทนไฟ ฯลฯ

Basis path testing

แปลว่า(Software Engineering) a white box test case design technique that used the algorithmic flow of the program to design tests

Corrosive waste

แปลว่า(Environmental Engineering) A waste that is outside the pH range of 2 to 12.5 or a waste that corrodes steel at a rate greater than 6.35 mm (0.25 in) per year. One of EPA's four hazardous waste properties.

basic lead chromate

แปลว่า(เคมี) PbCrO4. Pb (OH) 2 วัตถุสีที่ได้จากการต้ม lead chromate ammonia กับน้ำยา potassium หรือ hydroxide

Clarifier (sedimentation basin)

แปลว่า(Environmental Engineering) A tank in which quiescent settling occurs, allowing solid particles suspended in the water to agglomerate and settle to the bottom of the tank. The solids resulting from the settling being removed as a sludge.
